| 20120105033 | LIGHT AMOUNT DETECTING APPARATUS, AND LIGHT AMOUNT INFORMATION PROCESSING APPARATUS - A light amount detecting apparatus includes: a photoelectric converting element converting quantity of light inputted to current; a current/voltage converting device having a positive input terminal connected to a first terminal of the photoelectric converting element, a negative input terminal connected to a second terminal of the photoelectric converting element, a negative output terminal for reversing polarity of a current inputted to the positive input terminal and outputting it as a voltage, a positive output terminal for reversing polarity of a current inputted to the negative input terminal and outputting it as a voltage, a first negative feedback resistor connecting the positive and negative output terminals, and a second negative feedback resistor connected between the negative and positive output terminals, the current/voltage converting device setting the photoelectric converting element in zero bias and converting the converted current to the voltage; and an amplifying device for amplifying the converted voltage. | 05-03-2012 |
| 20110043128 | CIRCUIT DEVICE DRIVING METHOD AND CIRCUIT DEVICE - A drive method for a circuit apparatus includes: a cold cathode electron-emission element; a MOS transistor in which one of a source region and a drain region is electrically connected to one electrode of the cold cathode electron-emission element; a first voltage source electrically connected to another electrode of the cold cathode electron-emission element; and a second voltage source which is electrically connected to a semiconductor well region in which the MOS transistor is formed. The drive method is provided with: an electron-emission part forming process in which a first potential signal is outputted from the first voltage source and a second potential signal, which is different from the second potential signal, is outputted from the second voltage source so that a forward current flows in a p-n junction between the semiconductor well region and the one region when an electron-emission part is formed in the cold cathode electron-emission element. | 02-24-2011 |
